CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 248,799, dated October 25, 1881.

Application filed February 15, 1881.

To all whom it may concern Be it known that I, WILLIAM Sco'r'r, 0t Faulkners, Malden, in the county of Middlesex and State of Massachusetts, haveiuvented certain new and useful Improvements in Car- Oouplers, of which the following is a full, clear, and exact description.

This invention relates to car-couplings such as shown and described in the schedule annexed to the Letters Patent of the United States issued to me, dated January 4, 1881, No. 236,361 and it consists in a construction of the shackle-pin,of the upperand lowerjaws to receive, guide, and act as a support for the shackle-pin, and of the upper surface of the draw-head and otherwise, all substantially as hereinafter described.

In the accompanying plate of drawings this improved car-coupling is illustrated, Figure 1 beinga side elevation; Fig. 2, a central longi:

tudinal vertical section; Fig. 3, a plan view; Fig. 4, a section on line 00 m, Fig. 2; and Fig.

5, a cross-section on line 3/ Fig. 3, on a reduced scale.

In the drawings, A represents a draw-head, adapted at its portion 13 to be secured in any of the ordinary modes of the under side of a car, and at its front and projecting end, 0, to serve asacouplingforanothercarto be coupled to it in the making up of a train in accordance with this invention and the Letters Patent aforesaid. ,The coupling end 0 has an upper jaw, D, and a lower jaw, E, with an opening, F, between, a shackling or coupling link, Gr, having a rest, a, at each side of the lowerjaw, and a shackling-pin, H, all as shown and dc scribed in the Letters Patent aforesaid, except,however,ashereinal'terparticularlyspecified. The shaekling-pin H passes through the thickness of each jaw and across the opening F between them, and thus the strain or pull upon it is sustained by both jaws. This pin, at its front side, is provided with a projecting rib or flange, b, which extends along and for a portion ofits length from its lower end up ward, and at its lower portion its edge 0 runs at a vertical and acute angle to the length of the pin, and such portion at its lower part rests within the lower jaw, E, (suitably constructed therefor,) and at its upper part it projects over and above the upper incline face of such jaw. The upper portion of the rib b to the shackling-pin it. i a

H extends above the opening F between the jaws, and enters within the upperjaw, D, even when the pin is in the lower jaw, and the up perjaw is suitably shaped for the rib I) to pass up and down through the same as the pin is lifted or dropped in coupling or uncoupling. This rib guides the shacklingpin in its movements, and thus insures its entrance into the socket or opening (1 of the lowerjaw provided for it in the operation of the coupling.

The opening f in the upper jaw, D, for the shackling-pin H and its rib I), has a shoulder, L,t'or the rest of the lower end of thepin thereon when it is drawn up and out of its coupling position, from which rest the pin will escape and drop upon the concussion of the cars.

This enables a flying switching of the cars to be made.

M is a pin or shoulder located within the upper portion of the upper jaw, D, and in position for the rib of the shackling-pin to abut againstas thepin His drawn upward, and thereby prevents its detachment from the jaw I), while at the same time it allows sufficient upward movement of the pin to secure the uncoupling of the cars and to place it at rest, should it be so desired, upon the shoulder or rest L PIOXltlQtl for it. The upperjaw, D, at its bearing for the shackling-pin, is cored out, as atg, to reduce the frictional and contact surfaces of it upon the sides of the pin; and, again, the upper side of such jaw has a'raised rib, N, of sufficient height to cover and shield the top of the shackling-pin H when in its bearing in the lower jaw, and which rib, at one side of the pin 11, has a recess, h, of suitable depth for a chainconnection of the pin to fall into and below the upper surface of the raised rib N, and thus leave the upper surface of the jaw in every way free for the coupling of the adjoining car to pass over it without hinderance from the shackling-pin or its chain-connection, should such coupling-link happen to fall over and upon the draw-head.

The operation of this coupling, except as herein described, is substantially the same as in the said Letters Patent, and therefore it needs no more particular description herein.

The link G is beveled on its under side, as at l, to insure its riding up over a similar link on another car when coupling the two cars to gether.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, lS

1. The shackling-piu H, provided With the projecting rib b, in combination with the coupling-jaws D and E, the former having the fixed stop-pin M, arranged to strike the upper edge of the rib to limit the elevation of the pin, and the stationary rest L, arranged to support the lower end of the pin when elevated, substantially as described.

2. The two coupling-jaws 1) and E, the former having the fixed 'stoppin M and rest L, in combination with the shaehling-pin H, having on its front side the forwardly-projecting rib b, provided with the inclined edge, substantially as and for the purpose described.

3. The upperjaw, D, constructed on its up- K per side with the raised rib N, arranged around and adjacent to theopening for the shacklingpin, and having the lateral recess h, for the reception of the chain of said pin, substantially as and for the purpose described.

at. The upper coupling-jaw, D, constructed for the play of the shackling-pin through it, and provided with recesses 0r cored-out portions g, to reduce the frictional and contact surfaces between it and the pin, all substantially as described.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
